Kin-iro d'Corda or La Corda d'Oro~ Primo Passo (The Golden String or The Golden Cord)- 25 episodes based on RPG game and adapted into manga by Yuki Kuri
Hino Kahoko is just an ordinary student but her life changes when the music fairy gives her power to play the violin. She unwittingly agrees to enter the muscial concours against the music prodigies. The "La Corda d'Oro" is delicately drawn and filled with classical music. It's like a fine dining experience. The story is sweet and captivating at first but it became very serious near the end. The manga is ongoing as well, so if there would a be another season I hope it could redeem itself. I'm one Yunoki's crazed fan, I like his true personality. The operatic pop opening "Brand New Breeze" by Kanon is perfect for the anime and has a recall value.
